METALLIC SHINGLE.

SPECIFICATION forming part of Letters Patent No. 484,211, dated October11, 1892.

Application filed November 18, 1891. Serial No. 412,332- (No model.)

To all whom it may concern.-

Be it known that DAVID D. LUPTON, a citizen of the United States,residing at Philadelphia, in thecounty of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMetallic Shingles; and I do hereby declare the following to be asufliciently full, clear, and exact description thereof as to enableothers skilled in the art to make and use the said invention.

This invention relates to roofing of buildings, and particularly to thatclass of roofing formed of metallic shingles, and has for its object themore secure interlocking of the shingles with each other, the exclusionof water from beneath the shingles, and the avoid ance of buckling andopening of the joints between the shingles from changes of temperature.

To this end this invention consists in a construction of metallicplate-shingles having a flat nailing-surface, raised projections uponits upper surface, a cavity beneath it, a hooked flange upon one of itsedges, and an upwardly-inclined groove adapted to receive the hookedflange of similarshingles, as shown in the accompanying drawings, inwhich Figure 1 shows a top view of a metallic shingle embodyingthisinvention. Figs. 2, 3, and 4 show sections, respectively, in theplanes indicated by the dotted lines X X, Y

Y, and Z Z in Fig. 1, viewed in the direction of the arrows markedacross said lines; and Fig. 5 shows a portion of a roof covered withshingles embodying this invention.

This shingle consists of a single integral plate of ductile metal of arectangular or rhomboidal form, having margins 1 and 2 at the upperedges and practically parallel therewith, made flat, so as to lie uponand be fastened by nailing through holes 3 to the laths or boards 01'other like roofing-supports. Below the flat margin 1 and parallel withthe edge the plate is bent into a hooked groove 4, (see Figs. 2 and 3,)the opening of the groove being downward.

Below the flat margin 2 is a raised rib 5, commencing a slight distancebelow the hooked groove 4 and extending downwardly parallel with theedge of the margin 2 to a short distance from the end of such margin,

where it joins or turns into a short raised rib 6, extending to theedge. The portions marked 7 of the plate below and contiguous to thegroove 4 and the ribs 5 and 6are in the same plane as the margins 1 and2. The plate below the part marked 7 gradually rises above that plane tothe lower edges 8 and 9, where they are bent downwardly with inclinedsides, so as to present an edge in practically the same plane as themargins 1 and 2, and upon the edge 8 is a flange 10, turned under andupward, extending from aboutthe line of the rib 5 to the lower point ofthe shingle 11, at

which point the parts 8 and 9 are united by soldering or other means, soas to be fluidtight and to brace each other. The flange 10 is of suchdimensions as to hook under and fit in the hooked groove 4 of thecontiguous shingle.

The plate of the shingle, between ,the surfaces marked 7 7 and the bentlower edges 8 and 9, is stiffened by stamping a portion in relief, so asto remove the buckling incident to the bending and working of themargins or edges, and such relief may be of any ornamental or grotesqueform that taste or caprice may dictate with-in the limits of the ductileproperties of the metal and avoiding any depressions which would retainwater when the shingles are applied to a roof.

The shinglesof the construction above described are applied to the roofby nailing a lower row by' means of nails through the holes 3 3 in themargins 1 and 2, and hooks of plate metal may be secured to the roofbefore placing the first row of shingles into position, so as to engagethe flanges 10 of the shingles of the first row, after which theshingles of the next row are hooked by their flanges 10 into the grooves4 of the shingles of the first row.

The shingles of the second row cover the from the groove 4 of another inwhich it is hooked. The grooves 4, opening downward, shed water insteadof retaining it.

Having described this invention, what I claim is A metallicplate-shingle having flat margins extending from the upper corner uponthe upper edges for nailing, a downwardly-open hooked groove parallelwith and near one upper edge, adapted to engage an upwardlybent flangeon the lower edge of a similar plate-shingle, a stiffening-ribcommencingbe- 10w said hooked groove and extending parallel with theother upper edge near to the length of said second edge and thenreturned in parallel direction with the hooked groove across said edge,a gradually-raised plate extending below the hooked groove andstiffening-rib, terminating in downwardly-bent flanges parallel with thehooked groove and longer sides of the stiffening-rib and adapted DAVIDD.
